A tree is broken at a height of 7 cm from the ground and its top touches the ground at a distance of 24 cm from the base of the tree. find the original height of the tree.

pls explain with the working

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
